.. According to the datasheet, the features of the DK106 are as follows: 85 V 265 V wide-range AC power input. Double chip design with bipolar junction transistor (BJT) to save cost. Large-scale MOS digital circuit design with E class BJT ...
.. sensitivity of the circuit to minute changes in the input voltage. The sensitivity is 100 MHz per 5 volts, i.e., 20 MHz per volt. That means a 1-mV change on the input results in a 20-kHz change in the output frequency! So, how do you supply ... .. a PCB, purchased the (mostly) surface-mount components, loaded and re-flow soldered them onto the PCB, and then tested the design. Figure 1. VFC design that operates from 100 kHz to beyond 100 MHz with a single 5-V supply, providing ...
.. conducting some tests, it was found that the circuit operates quite stable, and the received sound is clear and sharp. To design the schematic and PCB, I used Altium Designer 23 and shared the project with my friends to get their feedback ...
.. been interest recently here in the land of Design Ideas (DIs) in a family of simple interface circuits for pulse width modulation (PWM) control of generic ...
.. voltage to approximately 3 V, which also limits the drive voltage to Q 1 ’s gate. The PCB (printed-circuit-board) design and the choice of coupled inductors for this power supply are critical for good performance. For the power ...
.. applications, however, exponential control of the conductance is preferred since voltage-controlled circuits use the “volt/octave” characteristic, whereby with each volt of additional control voltage, the cutoff frequency of the ...
.. A1a, combined with the surrounding discretes (Q1, Q2, Q3, etc.), make a VFC similar to the one described in this previous Design Idea, “Voltage inverter design idea transmogrifies into a 1 MHz VFC” ( Ref. 1 ). The U1ab, A1a, ...
.. also ramps on. The turn-on speed is a function of the TPS2331's 14-µA output current and the value of C 3 . The design uses the FETs based on the maximum resistance allowed in the dc path and the FETs' power-dissipation ...
